The creepy clowns are back in town, and this time they are promising to be “bigger and better” than ever.

Following the release of the new IT movie last week, an alleged group of terrifying clowns have taken to social media groups to share their plans to terrorise Perth residents.

In a post to the Clown Purge Australia Facebook page, an alleged group of creepy clowns promised to deploy ten clowns to several locations across Perth, including Mandurah, Kwinana, Rockingham, Bull Creek, Cockburn and Aubin Grove.

“After the release of IT, we're coming back bigger and better,” the post read.

“On Saturday we will be sending out 10 clowns to all different areas in Perth.

“Keep watch, see you all soon.”

The group also shared their plans to hide balloons with clues on where to find the clowns in several locations and called on residents to find and follow the clues.

“There will be each note attached to it, a clue to where us clowns will be [sic],” they wrote.
